Default please help!

thinking about going from a ss3600 to a ss4000 will there be any gains as far as track times bc im fustrated that i havent really gotten any quicker after h/c swap. i was running 8.15-8.20 in the 8th with the usual boltons plus stall and 3:73 gear. Now with new heads and 228 cam,fast92/92 but 3:42 gear now and built trans, same stall, im only running 8.0-8.05 and my 60ft time was the same with both setups witch was 1.80! on the dyno it made only 390 but i still thought i would be running at least 7.70s

That doesn't seem right...

What h/c setup are you running? Has it been tuned?

something is wrong. Yes a 4000 will 60 better but I would expect more from the present combo

I know neither sound like they've changed, but what is your raceweight and DA? Just trying to figure out what times it should be running.

Brian

do you have drag radials or et streets? you didnt mention that and with a h/c/stall that is an absolute must.

You need to compensate for a difference in air. My car varies by up to a half second depending on what kind of air I am running in. Is it possible that you got your best bolt-on times in like March or late October when it was much cooler and less humid than now? A good thing to do every time you are at the track is to find a "regular" and ask them what the DA is. Chances are they will have a weather station. Or you can go buy a weather station online if you go to the track a lot.
